This is obviously hypthetical, as we have no idea what the actual facts are nor should we. But imagine a situation where she did indeed receive cuts on her fingers in a fight with Antony, but - again making this up - he was uninvolved in the cuts. They're yelling, he yells, she drops a glass whatever.
The situation she and the lawyers have created - again they ACTIVELY chose to send images and private text messages to the press - is that Antony cut her. That is what the news stories and images being juxtaposed is designed to do.
And when these are shared by major twitter accounts, this just creates the narrative.
Now maybe it's entirely true, and Antony thus deserves all of the hate and damage to his life that is to come. But. What if it's not?
There's only one reason to go to the press imo: you and your legal team feel that you're better served there then going through legal channels. Whether that's because you want to pressure into a settlement, or you're not convinced of your ability to win. But for me, personally, the second a single-party goes to the tabloids, there have to be questions asked about the motivations to do so.
The Greenwood case is actually an excellent example of this: the parties did NOT want any of it going to the press. It was leaked agains the desire of the victim, which is probably related to why said victim withdrew.
